Psychometric properties of the Turkish Community Integration Questionnaire-Revised in stroke survivors.

Abstract

There is a need for a reliable and culturally appropriate Turkish instrument to evaluate community integration after stroke, as the Community Integration Questionnaire-Revised (CIQ-R) has not previously been validated in Turkish. This study aimed to translate and culturally adapt the CIQ-R and examine its validity and reliability in stroke survivors. The adaptation process followed internationally accepted guidelines. A total of 166 individuals with stroke were included, and test-retest reliability was assessed in 146 participants over a 2-week interval. Construct validity was examined using exploratory and confirmatory factor analyses, and internal consistency and test-retest reliability were evaluated. The Turkish CIQ-R demonstrated acceptable internal consistency (Cronbach's alpha = 0.775) and excellent test-retest reliability (intraclass correlation coefficient = 0.952). Exploratory factor analysis supported a 14-item, four-factor structure, which was confirmed by confirmatory factor analysis with good model fit (χ 2 /df = 1.609, Comparative Fit Index = 0.950, root mean square error of approximation = 0.060). These findings indicate that the Turkish CIQ-R is a valid and reliable instrument for assessing community integration in individuals with stroke. The availability of this tool may support clinical practice, outcome evaluation, and cross-cultural research in stroke rehabilitation.
